  Jul 11 10:08:58 BaylyJ4 kernel: [  888.020009] PM: Error -12 creating hibernation image

  When hibernating, if there isn't enough free memory, the hibernate
  file cannot be created (as expected), however instead of the system
  reporting this and returning to the previous state, it appears to
  freeze allowing no input - Ctrl + Alt + F1 doesn't give me a shell
  login prompt. The machine will remain running indefinitely and has to
  be power cycled. Upon restart, I am given a standard login prompt.

  Expected behaviour would be that the OS returns the user to a state
  where they can safely close any critical applications.

  As an aside, I'm investigating why my system will not hibernate when I
  have a total of 6GBi swap (2GBi + 4GBi), of which 5MBi is used, and
  only 2GBi of RAM installed.
